Explore Sweden in stunning interactive 3D
CityScape 3D is a web-based geospatial application engineered for the three-dimensional exploration, visualization, and quantitative analysis of urban environments. By integrating real-time vector data retrieval with high-performance WebGL rendering, the platform dynamically transforms 2D building footprints into immersive, extruded 3D cityscapes. It empowers urban planners, spatial researchers, and GIS professionals to interactively query specific Areas of Interest (AoI), manipulate visual parameters, and extract critical morphological metrics to facilitate advanced spatial understanding.
Core Capabilities:
- Interactive Spatial Querying: Features a dynamic 2D mapping interface that allows users to precisely delineate custom Areas of Interest (AoI) via bounding box selection, complete with automated spatial constraint validation (max 25 km²) to ensure optimal query performance.
- Hardware-Accelerated 3D Rendering: Employs WebGL-based extrusion (via deck.gl/Pydeck) to generate interactive, high-fidelity 3D representations of the urban fabric. Users can manipulate camera pitch, apply vertical exaggeration (height scaling), and toggle wireframe modes for structural analysis.
- Real-Time Urban Morphological Analytics: Features an automated computational module that calculates and visualizes quantitative metrics for the selected AoI in real-time, including total building density, mean/maximum height distributions, and dominant architectural typologies.
- Parametric Visual Control: Offers granular control over the 3D rendering environment. Users can adjust object opacity, apply thematic color palettes, and enable automated camera rotation to highlight specific urban characteristics and spatial relationships.
- Semantic Data Parsing: Intelligently queries and parses OpenStreetMap (OSM) tags to infer structural heights and differentiate building types, ensuring rich data representation even when explicit physical measurements are absent in the source data.
- Standardized Geospatial Export: Facilitates downstream spatial analysis and computational modeling by allowing users to export the extracted geometries and attribute tables into industry-standard formats (GeoJSON and CSV).
Target Applications & Use Cases
